Answer Share Decay

Answer Share Decay is the rate at which a client's presence inside AI-generated answers falls when no one maintains the sources those engines cite. Unlike a keyword ranking, which holds until a competitor outranks it, an AI answer citation can vanish when a cited page is rewritten, a Reddit thread goes stale, or a competitor publishes a cleaner answer to the same prompt. Agencies that treat AI visibility as a one-time audit watch share slip within weeks; those that re-run prompts on a fixed cadence catch the drop while it is still cheap to fix. Pallix maps which domains and sources shape AI recommendations, so a decay in share points back to a specific lost citation rather than a vague ranking dip. With 69% of marketers publishing more AI content than last year, the volume of competing answers keeps rising, which shortens the half-life of any citation an agency wins.
